* Fixing a bug where the max burst rate for the state category was being set as unlimited, causing connections to child agents to saturate bandwidth
* Upped the example default drip rates to 1000 bytes/sec, the minimum granularity for the token buckets
* Added contacts_per_collision to the ODE config section. This allows you to reduce the maximum number of contact points ODE will generate per collision and reduce the size of the array that stores contact structures
* Added a new [Startup] config option called use_async_when_possible to signal how to run operations that could be either sync or async
* Changed Scene.ForEachClient to respect use_async_when_possible
* Fixing a potential deadlock in Parallel.ForEach by locking on a temporary object instead of the enumerator (which may be shared across multiple invocations on ForEach). Thank you diva
* Avoid allocating an Action<IClientAPI> object every round of the OutgoingPacketHandler
* Removed unnecessary semi-colon endings from OpenSim.ini.example [InterestManagement] section
* Only initialize Util's SmartThreadPool if it is actually being used
* No longer initializing Util's SmartThreadPool with a custom max stack size. From MSDN: "Avoid using this constructor overload. The default stack size used by the Thread(ThreadStart) constructor overload is the recommended stack size for threads."
* Changed Util.FireAndForget() to use any of five different methods set with async_call_method in the [Startup] section of OpenSim.ini. Look at the example config for possible values
* Replaced calls to ThreadPool.QueueUserWorkItem() with ThreadPool.UnsafeQueueUserWorkItem() since OpenSim does not use Code Access Security sandboxing
* OnQueueEmpty is still called async, but will not be called for a given category if the previous callback for that category is still running. This is the most balanced behavior I could find, and seems to work well
* Added support for the old [ClientStack.LindenUDP] settings (including setting the receive buffer size) and added the new token bucket and global throttle settings
* Added the AssetLoaderEnabled config variable to optionally disable loading assets from XML every startup. This gives a dramatic improvement in startup times for those who don't need the functionality every startup
Http-in and makes the host name for URL generation configurable.
Applied with changes:
llGetSimulatorHostname was not changed, because the change breaks
existing behavior and carries a data exposure risk. That value needs
to be configurable, the proposed fixed change is not acceptable.
sweep every 10 minutes. If any texture data is older than 12 hours, it is
regenerated and the memory cache is refreshed. After each decode, the thread
delays for 5 seconds.
setting the path for it. This commit introduces NEW DEFAULT BEHAVIOR. To
retain the old behavior (eternal cache) you will need to change your OpenSim.ini
and set the timeout to 0.
Add ability to silence IRC relay of region joins and quits from certain users
This is useful for admins who wish to remain hidden, or service bots.
Thanks RemedyTomm
this commit finally adds the VivoxVoiceModule: it supports positional
as well as conference call type voice (currently only per region
server), region and parcel voice, speaker indication (LL client
family), direct avtar-to-avatar voice chat. NOTE: you need to obtain
an customer admin account from Vivox to be able to use this module ---
DON'T ask me about how to about an admin account, i've NO clue, we
just wrote this code.
Set av_capsule_tilted to false in opensim.ini. Default is true, so there is
no change in avatar behavior (and no breaking of existing content which
relies on the tilted capsule).
This commit straightens up the avatar capsule so it behaves consistently
(e.g. same collision behavior against prims regardless of which direction
the avatar is coming from; ability to fit through narrow doorways).
Please note this introduces other side effects which have not been fixed.
In particular:
* The avatar frequently falls through the terrain if it is not flat, though
the avatar behaves pretty well on flat terrain. This requires investigation
of the ode terrain collider.
* The apparent foot position of the avatar with respect to the ground
is changed. This requires investigation of the avatar height/capsule height.
Please consider this as work in progress.
option for LLUDPServer. On windows .NET the default socket receive
buffer size is 8192 bytes, on recent linux systems it's about
111K. both value can be a bit small for an OpenSim instance serving
many clients. The socket receive buffer size can be configured via
an OpenSim.ini config option
- adds a general catch clause to LLUDPServer.OnReceivedData() to
prevent it submerging when an unexpected Exception occurs.
This change moves texture send processing out of the main
packet processing loop and moves it to a timer based
processing cycle.
Texture packets are sent to the client consistently over
time. The timer is discontinued whenever there are no
textures to transmit.
The behavior of the texture sending mechanism is controlled
by three variables in the LLCLient section of the config
file:
[1] TextureRequestRate (mS) determines how many times per second
texture send processing will occur. The default is 100mS.
[2] TextureSendLimit determines how many different textures
will be considered on each cycle. Textures are selected
by priority. The old mechanism specified a value of 10 for
this parameter and this is the default
[3] TextureDataLimit determines how many packets will be sent for
each of the selected textures. The old mechanism specified a
value of 5, so this is the default.
So the net effect is that TextureSendLimit*TextureDataLimit
packets will be sent every TextureRequestRate mS.
Once we have gotten a reasonable feeling for how these parameters
affect overall processing, it would be nice to autonmically manage
these values using information about the current status of the
region and network.
Note that this also resolves the pathologcal problem that
previously existed which was that a seated avatar generated very
few in-bound packets (theoretically) and would therefore be the
least able to retrieve the images being displayed by a
projector script.
We've encountered problems with textures never fully downloading and
objects not moving or being deleted (from the client's point of view)
even when the bandwidth settings on the client have been set very
low. This can happen over reasonably lossy links (eg you're on the
other side of the world from the server) as the server retries 3 times
and then gives up.
Whilst its possible to set ReliableIsImportant, this forces the server
to keep retrying no matter what which potentially could lead to
problems. This patch allows for the setting of MaxReliableResends
explicitly (is set to 3 normally) in OpenSim.ini so if you know you
will have clients connecting with poor connections you can set it a
bit higher (10-15 works quite well even for very poor connections).
This may break a lot of things, but it needs to go in. It was tested in standalone and the UCI grid, but it needs a lot more testing.
Known problems:
* HG asset transfers are borked for now
* missing texture is missing
* 3 unit tests commented out for now
default but can be enabled in OpenSim.ini. If enabled, things can be sold
for $0. Other amounts will cause the buyer to see a message and the transaction
will fail.
Move json stats to non-published resource name
Remove well-known resource name for json stats,
creating dynamic uris with private keys and add
a user configurable resource name for region owner usage.
Different people using Hippo 0.5.1 report that trying
to send group instant messages crashes the viewer
(Hippo 0.5.1). This is the case even for empty groups
or if all group members are online.
Don't allow packets to be resent before they have actually been sent for the
first time. Switch from serializing a packet to get it's length to the LibOMV
provided Length property. Fix resend timing. Fix the use of dangling references
to Acked packets. Fix the packet handler to play nice with the packet pool.
Fix the packet pool. Add data block recycling to the packet pool. Packet pool
is now ENABLED by default. Add config option to disable packet and data block
reuse. Add ObjectUpdate and ImprovedTerseObjectUpdate to the packets being
recycled.
The attached patch provides the necessary infrastructure to support
security and authentication features of the xmlrpc server.
* Read/Write keys for accessing a Group's xmlrpc service.
* Requiring user session verification for write operations.
- Adds an admin_modify_region call to allow changing of parcel voice
settings and changing of public/private status
- add boolean "public" and boolean "enable_voice" to
admin_create_region XmlRpc call to allow specifying of
public/private status and to allow enabling voice for all parcels;
also added config variables to allow setting of defaults for those
- fixing cut-and-paste artefacts
* Refactors the xmlrpc calls to a single location to
make it easier to debug and include alternative
xmlrpc call mechanisms
* Includes an alternative xmlrpc call mechanism that
sets HTTP Keep-Alive to false which solves nearly all
System.Net exceptions on some windows environments
Added is a patch that adds a rough Groups implementation. This patch allows
the creation, adding and maintaining Groups, Roles and Members. Work has begun
on a very naive implementation of messaging, and minimal support for notifications
{no attachments yet}. Proposals are not yet supported, but are on the to-do list.
This implementation is not active by default, and must be configured in
OpenSim.ini to become active.
Fixes Mantis #3421
Change the agent/avatar events subscriptions to just OnNewClient. The data only needs to be sent once and keeping track of log ins/movements is not required. This will also send cloud data to child agents so that they can see clouds above neighbouring regions not just regions that they have visited.
Added safemode config to Standalone Hypergrid, similar effect to AllowRegionAccessToInventory in Inventory Server. Everyone should have these vars set to their default values except me!
Attached is a patch which enabled through an OpenSim.ini option the ability
to read long notecard lines. Currently although the data is read from
the notecard it is truncated at 255 characters (same as for the LL servers.
This patch allows the setting of that limit to a different value.
; Maximum length of notecard line read
; Increasing this to large values potentially opens
; up the system to malicious scripters
; NotecardLineReadCharsMax = 255
this allows for save/restore functionality using notecards without
having to worry about very short line length limits.
* In most cases, the setting in OpenSim.ini.example is taken as the canonical one since this is the file virtually everyone ends up using
* OpenSim will start up with a blank OpenSim.ini, in which case sqlite is the default database (as before)
The built-in default is OpenSim, unless a user server url is given, then
that is used, unless "shard" is also goven, then shard takes precedence.
The defult in OpenSim.ini is "OpenSim" for compatibility.
The change makes two principal implementation changes:
[1] It removes the hard coded set of possible asset server client
implementations, allowing any arbitrary implementation that has been
identified to the PluginLoader as an appropriate extension. The
extension point for asset server client extension
is /OpenSim/AssetServerClient. All of the old configuration rules have
been preserved, and any of the legacy configuration values will still
work as they did before, except the implementation is now loaded as a
plug-in, rather than as a hard-coded instantiation of a specific class.
The re-hashing of IAssetServer as an extension of IPlugin made upgrading
of the implementation classes a necessity.
Caveat: I have not been able to meaningfully test the crypto-grid
clients. I believe they should work correctly, but the refactoring
necessary to handle plug-in based initialization (vs constructor-based
initialisation) admits the possibility of a problem.
[2] The asset cache implementation, previously introduce as a hard-code
class instantiation is now implemented as an IPlugin. Once again the
previous (configurationless) behavior has been preserved. But now it is
possible for those interested in experimenting with cache technologies
to do so simply by introducing a new extension for the asset cache
extension point (/OpenSim/AssetCache).
I've tested all of the configuration settings, after applying the patch
to a newly extracted tree, and they seem to work OK.
This changeset add the RegionReady module code. The module sends a
message on a configurable channel when an oar file has finished
loading or if the script engine has emptied its queue for the first
time (eg server startup). Config is something like this:
[RegionReady]
enabled = true
channel_notify = -800
The module also knows if there was an error with startup.
* This adds more explanation for the new proxy settings in OpenSim.ini.example
* Also does some formatting correction
* I did some additional reformatting on top of that
* This option makes OpenSim use the usual db based asset service in standalone, and the grid based one in grid mode
* The other options can (local, grid, etc) can still be used explicitly as before
* Also change OpenSim.ini.example and the surrounding explanative text
* Adding an option to use the tree module to manage the trees in the simulator (grow/reproduce/die)
* Setting it to off by default in an effort to reduce the number of threads in use by default
* You can also turn it on in a 'one off' way with 'tree active true' on the console. To 'one off' turn it off, it's 'tree active false'. The permanent way to do that, however is in the opensim.ini.
* This allows configuration of the assetset and library control file paths to be other than ./inventory/Libraries.xml and ./assets/AssetSets.xml
* This is controlled via the LibrariesXMLFile and AssetSetsXMLFile configuration settings in [StandAlone] in OpenSim.ini (in standalone)
and via the user and asset config xml files for grid mode
* Thanks to SirKimba for the patch
The attached patch ads an OpenSim.ini option (AutomaticLinkPermission)
which when enabled makes PERMISSION_CHANGE_LINKS to be granted to
scripts by default. When enabled llGetPermissions will always return it
as granted and llCreateLink//llBreakLink will succeed without
doing llRequestPermissions. ONLY ENABLE THIS IN TRUSTED ENVIRONMENTS.
The patch also fixes a minor bug in llCreateLink
related to a potential dereference of a null client object.
* Disabled by default (see OpenSim.ini.example for how to enable)
* Saves exceptions to a folder on disk (default "crashes") when enabled.
* These reports can then be uploaded or posted to help debug an error.
* This allows one to override normal OpenSim permissions and prevent non-gods from editing any scripts. This allows edit ability
to be rescinded after it has been given, and prevents the security hole where a single script with liberal perms would allow code changes.
* The default setting remains the existing one of never overruling normal edit permissions.
* These two settings may be enough to stop non-gods entering artbirary script code in a closed grid/standalone configuration.
